Application filed December 10, 1918.

My invention relates to sliding bolt mechanism of the kind generallyused on bags, suit cases and like articles for fastening swinging framesections together, and its object is to provide a durable and economicalsliding bolt mechanism of this general type which can be madeprincipally out of sheet metal without detracting from its strength orappearance. Another object of my invention is to provide sliding boltmechanism which can be made up from a minimum number of parts and inwhich the tendency for the parts to become loose and rattle will bereduced to a minimum.

I attain these and other objects of my invention in the device set forthin the following description and accompanying drawings in which likereference characters refer to cor esponding parts.

In the drawings:

Figure 1 is a perspective View of my device before it is attached to thetion of a traveling bag;

Fig. 2, a longitudinal sectional view;

Fig. 3, a bottom plan view, and

Fig. 4, a transverse sectional view taken on line 6U.,23 in Fig. 3.

My device generally comprises a boXlike base member or casing 2 having atop face portion or wall 3, side walls 4, 4 and end walls 5, 5. The endwalls 5, 5 are provided with projecting lugs 6, 6 which serve to clenchthe casing to the top plate of one of the bag frame members. The topwall 3 of the casing is provided with an elongated,

frame secrectangular-shaped opening 7 The under side of the top wall'3of the casing is pro vided with two pair of alined recesses 8, '8 and 8,8, the recesses of each pair extending away from the side edges of theslot 7. Sliding longitudinally upon the top wall of the casing 2 is theslide proper or finger piece 9, the same comprising a rectangularbox-like casing substantially of the general configuration of the loweror base casing 2 but slightly smaller than the latter. The upper casing9 is provided with end walls BAG-FASTENER.

10, 10 each of which has bent inwardly from its lower edge a pair ofprojecting lugs 11, 11. Resting on these lugs a flat spring plate 12 ofa surface area SllfflClGllt to substantially close the under side of theupper casing 9 and having its body portion provided with a plurality ofapertures 13, the

purpose of which will presently appear. Dcpendlng from the under slde ofthis plate is a locking post formed out of a single p iecc of sheetmetal folded midway of its extremities and brought together so as toform the post proper 14:, the upper extremities of the metal beingseparated to form the side walls 15, 15 having spaced lugs 16, 16projecting from their upper edges respectively. These lugs 16, 16 passthrough the apertures 13, 13 on each side of the center of the springplate 12 and are bent outwardly against the top side of the spring plateand form brackets or supports for holding up the locking post. The endedges of each of the side walls 15, 15 are slit and bent to form theoutwardly projecting lugs 17, 17 which project at right angles from thewalls 15, 15 adjacent to each end thereof but slightly below the topedges of these walls.

The parts are assembled in the following manner. The lugs 16 on the topedges of the locking post are passed through the apertures 13 in thespring plate and bent outwardly at right angles. The spring plate isthen inserted into the upper casing 9 so that its end edges rest on thelugs 11, 11 projecting from the bottom edges of each end of the casing.The uppericasing 9 is then placed over the opening 7 in the top wall 3of the lower or base casing 2 so that the locking post extendsdownwardly therethrough. The lugs 17 17 at each end of the locking post,which up to this time have not been bent out of the plane of the sidewalls 15, 15, are then turned outwardly at rightangles to the walls, thespring plate 12 having been pulled downwardly by the lugs 16 asufiicient distance to enable the top edges per casing 9 is given anendwise movement on the top of the lower casing 2 the upper edges of thelugs 17 at one end of the post slide out of these recesses 8, 8, and atthe end of the sliding movement of the upper casing, snap into theadjacent recesses 8, 8. The recesses 8, 8 and 8, 8 serve to hold thecasing at each end of its sliding movement. By utilizing a spring plateto support the locking post it is possible to make allowances forvariations in the thickness of the metal forming the casing and to drawthe parts together in their assembled relation even though the same arenot formed to exact dimension. Since the spring plate is seated on lugsin the casing and the lugs at the top of the post are seated against thetop of the spring plate it is possible to assemble the device by hand,thereby dispensing with the riveting and other machinery usuallyemployed for assembling purposes. The feature of having the top of thelocking post made box shape so that its top Walls are spaced apart Whereit joins the spring plate serves to prevent the post from tilting andbreakingoff as is sometimes the case wvhen the pest is made of a singlethickness of metal. The feature also of forming the post out of a foldedpiece of metal enables a light gage of metal to be used at the same timepreserving the strength of the post proper. While I have shown laterallybent lugs for guidingthe post along the top Wall of the base it isobvious that I may utilize any other guides when desirable. It should benoticed that the sliding casing presents a flush surface on all. sidessince in the construction of my device it is not necessary to pierce thewalls of the casing when fastening the parts together. The seating ofthe spring Within the sliding casing enables me to substantially concealthe same and also to eliminate the inner shell member usually employedfor attaching the post to the casing.

ent is:

1. In a fastening device for bag frames and the like a base adapted tobe secured upon one of the bag frame sections,;a casing slid-ablyarranged upon said base, a spring plate mounted Within said casingand ade pending post connected with said spring plate.

In a sliding bolt .u'iechanism for bag fas toners and the like a baseadapt-ed to be secured to one of the bag frame sections and having anopening therein, a member slidably arranged upon said base ovcrsaidopening and a depending post carried by said member and extedingdownwardly through said opening, the said post beingformed out of asingle piece of metal folded upon itself and having its extremitiesterminating at the uppe end of said post.

.3. In a slidingbolt mechanism for bag fasteners and the like thecon'ibination with a base adapted to be secured to one of the bag framesections and having. an evening therein, a member slidably mounted. uponsaid base over said opening" and a depending post carried by saidmemberand extend ing downwardly through said opening, the said postbeing formed out of a single piece of sheet metal doubled upon itselfand brought together to form the post proper but separated atits upperextremity at its junction with said sliding member.

In testimony whereof I have hereunto set my hand this 5th day ofDecember 1918.
